|---|---|---|---|
| Expense ratio | 0.88% | 0.09% | Lower is better — it compounds against you every year you hold. |

| Average volume | 499,250 | 46,698,705 | Liquidity — matters most if you trade size. |

| Sharpe ratio | 0.91 | 0.91 | Return per unit of risk. Higher is better. |

AIQ Signal Divergence

Only CPER
- Bollinger Band Squeeze — neutral, volatility, short horizon
4 bullish / 1 bearish / 1 neutral, conflicted
Only SPY
- EMA Ribbon Expansion Bullish — bullish, trend, medium horizon
- 52-Week High Proximity — bullish, risk, long horizon (1.2%)
- Uptrend Structure Active — bullish, trend, long horizon

What would flip this result
A state, not a forecast. These are the specific, observable changes that would reverse the verdict — not a price prediction.
- 1CPER closes the Quality gap — currently 39 points behind, the largest single contributor to SPY's edge.
- 2CPER's Bollinger Band Squeeze turns directional — it is neutral today and would confirm a change in trend.
- 3SPY's conflicting signal state resolves bearish — it currently carries 4 bullish and 1 bearish rules at once.
- 4A regime shift changes factor weighting — Quality and Value carry the heaviest weights in the composite, so a rotation toward either would move the result most.

How this comparison is scored
The Algovestiq AIQ Score composites four factors — Quality, Value, Momentum and Risk, each carrying a fixed weight. Sentiment is reported separately as SentimentPulse and is not folded into the composite. Scores refresh every trading day, and this page regenerates from the latest snapshot rather than being written once.
The verdict names a leader, states how broadly six independent evidence groups agree, and rates how durable that conclusion is given the score gap, its recent trajectory and the current signal state on both names.
